STOP-MOTION DEVICE FOR WOOL-COMBING MACHINES.

SPECIFICATION forming part of Letters Patent No. 312,271, dated February 17, 1885.

Application filed December 14, 1883. (No model.) Patented in England February 9, 1883, No. 711.

To all whom it may concern.-

Be it known that we, JONATHAN HOLDEN, JAMES BURNLEY,and J OSEPH FAwELL, subjects of the Queen of Great Britain, residing 5 at Bradford, in the county of York, England, have invented anew and useful Improvement in Stop-Motion Devices for Wool-Combing Machines, such stop-motion devices being actuated by the breaking of the sliver, (for which wehave obtained aPatent in England No. 711,

dated February 9, 1883,). of which the following is a specification.

The said invention relates to an automatic or self-acting arrangement for stopping Nobles r 5 and other combing-machines of similar'construction when the sliver breaks during the operation of combing, either in consequence of a lap forming on the drawing-off rollers or from the sliver adhering to the leather, or

from any other cause,whereby it is prevented from passing to the sliver-can placed to receive it. The broken sliver, when the machine is allowed to continue running, causes damage to the fibers, makes waste, and obstructs the For the purpose of carrying out our invention, we attach below one of each set or pair of the drawingoft' rollers and on the same spindle a cam or tappet, which, when required,

gives a slight horizontal movement to a bent lever, which lever works upon a stud fixed in the center of the combing-table, suchmovement being communicated only when a block or foot-piece attached to a falling lever is 3 5 dropped between such hereinbefore-mentioned cam or tappet and the end of the bent lever.

\Vhen the machine is working and the sliver unbroken, the fallinglever, to which the block or foot-piece is attached, is held up by the 0 sliver, and the block or foot-piece is thereby prevented from falling between the cam and bent lever, there being a small space between such cam and bent lever, so that the cam can revolve without touching the bent lever; but

5 as soon as the sliver breaks, the block or footpiece on theend of the falling lever and supported thereby drops into the space between the cam and the end of the horizontal bent lever. This lever then receives a slight movement from the cam sufficient to press forward the lower end of a catch-lever with which it comes in contact, the upper end of the catchrod being thereby lifted out of a notch in the starting-rod into which it had been placed, and the starting-rod, being thereby released, is 5 5 moved by a spiral spring, and by means of a projecting finger actuating the belt-fork the movement of the starting-rod pushes the driving-belt of the machine from off the fast onto theloosepulley,therebystoppingthemachine.

In order to enable our improvements to befully understood, we will proceed to describe the same by reference to the accompanying drawings, in which Figure 1 represents an elevation, with portions shown in section, of part of a combingmachine to which our automatic stop-motion is applied. Fig. 2 is a transverse sectional elevation of the machine Fig. 2*, a detail, e11- larged, of the lower part of Fig. 2. Fig. 3 is a sectional plan of the same. Fig. 4 shows a portion of Fig. 3 on a larger scale. Fig. 5 shows a portion of Fig. 1 on a larger scale.

Similar letters of reference in all the figures of the drawings represent similar parts.

On the lower part of the spindle A of the drawing-off rollers B we secure the cam or tappet O, which cam revolves with the drawingoft roller.

In the center of the table D of the combing- 8 machine is fixed the stud E, upon which works horizontally the bent lever G, which has at each of its extremities,H, avertical pillar, I, having a stud, J, projecting horizontally from its upper part, upon which works the falling lever L. 5 This lever has ablock or foot-piece, M, attached to it at one end, and at the other end a counterpoise-weight, which partly balances the wedge M. The horizontal lever G, when pressed back, comes in contact with the bottom 9 end of the catch1ever N, which is fulcrumed at Z 011 the cross-stay X, fixed between the two upright columns of the combing-machine. The top end of this rod N is normally kept in position in a notch, O, in rod P, (until a sliver breaks,) by a spiral spring, D. This spring D is fitted over the head of the rod N and secured to the top frame, E of the machine. The bottom end of the catch-lever N being pressed back, the top end of the lever is lifted 1 0 out of said notch at O in the starting-rod P, and this 1ever,bein g thereby released,is moved by the spiral spring at Q in a horizontal direction, thereby pressing the adjustable projecting finger R against the adjustable belt-fork S on the slide-rod P, by which the belt is removed from the fast pulley T onto the loose pulley U, whereby the machine is stopped. The bars or rods P and P are supported in bearings C, secured to the columns W. The unbroken sliver V, supporting the falling 1ever Lwith its block or foot-piece M, is shown on the left side of Figs. 1 and 5; but on the right-hand side of the same figure the sliver is shown broken, the block or foot-piece M on the end of the falling lever L has dropped in between the revolving cam G and against a socket, H, connected to the end of the bent lever G, and the cam in its next revolution having communicated, through the block or foot-piece M, a slight movement to the bent lever G, the catch-lever N is thereby pressed back, the starting-rod P is released, and the driving belt pushed upon the loose pulley U, this movement, caused by the breaking of the sliver, stopping the machine. Each of the two pairs of drawing-off rollers, usually employed in a N obles or similar combing-machine, is fitted with a cam, as described, and is able to give a similar motion to the two ends of the bent lever G, in the manner described. The slivers from the two smallercircular combs Dpass from the drawing-off rollers through the funnel G". Y The drawing-off rollers B receive their motion from the vertical shafts E, to which they are geared by two pinions, F, and intermediate wheels, G. The drawing-oft rollersBgive motion to the drawing-ofl rollers B by means of flutings in the surfaces of both rollers fitting into one another.

The action of the revolving cam O on the block or foot-piece M, when, by the breaking of the sliver, the wedge has dropped and lodged between the cam and the end of lever G, (see the right-hand side of Fig. 2,) necessarily imparts, as stated, a slight movement to this lever, and the latter being then, as previously stated, in contact with lever N, this lever N is slightly moved and released from its detaining-notch, thus permitting the movement of the startingrod to shift the belt and stop the machine.

We claim The combination, with the spindles of drawing-ofi' rollers, of the cams or tappets G, stud E, bent lever G, standards I on the extremities of said bent lever, studs J, weighted levers L, provided with blocks or pieces M, catchlever N, fulcrumed on a cross-stay, spring D", sliding rod 1?, provided with a notch, 0, spring Q, finger R, and strap-fork S, the combination being and operating substantially as shown and described, and for the purpose set forth.
